    摘要： A retractable driven track system for wheeled vehicles includes a frame on which is mounted an endless flexible track, a pivotable linkage coupled at a lower end thereof to the frame, and adapted for coupling at an upper end thereof to the underside of a vehicle, a selectively actuable actuator operatively coupled to the frame or linkage to selectively raise and lower the track relative to the vehicle when the track is mounted to the vehicle, a drive selectively driving rotation of the track relative to the frame so as to assist in at least forward traction of the vehicle when the track is driven by the drive and the track is lowered into contact with soft ground under the vehicle.

    摘要： A track system includes a primary wheel structured to be rotationally attachable to a vehicle, a frame rotationally supporting a plurality of secondary wheels; a sub-frame supported by the frame. The sub-frame rotationally supports the primary wheel. The primary wheel and the plurality of secondary wheels support an endless track thereabout. A fastener secures the frame to the sub-frame and prevents pivoting of the frame relative to the sub-frame about the pivot axis. The fastener is disengageable. The frame is pivotable relative to the sub-frame about the pivot axis when the fastener is disengaged. The fastener is re-engageable to secure the frame to the sub-frame in any one of a plurality of different adjustment positions. In some implementations, a pivot member extends in a vertical direction between the sub-frame and the frame and defines a pivot axis of the frame.

    摘要： A rim includes a wall, a first annular projection, and a second annular projection. The wall has a first end and a second end. The first end includes a first opening, and the second end includes a second opening that communicates with the first opening to define a bore for a shaft of a track roller. The first annular projection and the second annular projection, which are configured to engage a track, extend radially from the wall. The first annular projection includes a first flange that is configured to constrain movement of the track in a first axial direction. The first flange includes a plurality of notches. The second annular projection includes a second flange that is configured to constrain movement of the track in a second axial direction that is opposite to the first axial direction.
